## Description

An IBusProperty is an UI component like a button or a menu item which shows the status of corresponding input method engine property. End user can operate and see the current status of IME through these components. For example, ibus-chewing users change the English/Chinese input mode by pressing ctrl-space or click on the Eng/Chi switch button. And the IBusProperty shows the change correspondingly.
